Issues in original projects #22

My work on fixing upstream issues, or at least opening new issues in this repo to track them.

objc issues:

• mem::swap doesn't work with Objects SSheldon/rust-objc#6
  • Tracked in Unstable: extern type support #73
• Adding a method isn't ergonomic SSheldon/rust-objc#12
  • Tracked in Better class declaration #30
• Implement Encode for more types SSheldon/rust-objc#26
  • The system has been improved in Add RefEncode, and make Encode bounds required #14, pointers to pointers now work.
  • And the rest is fixed by More Encode and RefEncode implementations #52.
• Should Object and other runtime types be Send/Sync? SSheldon/rust-objc#44
  • In Add objc_sys crate #19 we ensure that the types are not Send, Sync and Unpin by default
  • And then they were made the correct thing in Send and Sync fixes #94.
• Sending messages is inefficient because of selector lookup SSheldon/rust-objc#49
  • Tracked in Add static selectors #104
• Consider making objc no_std compatible SSheldon/rust-objc#51
  • Worked on in More no_std support #6, Prepare for a time when we can make the crates no_std #152 and Remove libstd from objc-sys and block-sys #305.
  • Remaining is mostly C types from std::os::raw, CStr and CString - see tracking issues Tracking Issue for core_ffi_c rust-lang/rust#94501 and Tracking Issue for feature(core_c_str) and feature(alloc_c_string) rust-lang/rust#98314.
  • Unsure about stuff in rc::autorelease?
  • Conclusion: This will happen at some point, but it requires higher MSRV and more compiler support.
• Add custom derive for Encode SSheldon/rust-objc#52
  • Tracked in derive macros #55
• API for passing already nul-terminated strings to avoid allocation SSheldon/rust-objc#54
  • Tracked in Add a terminated dependency and use NulTerminatedStr for inputs #113
